Bruce Lawson’s personal site  : Structured data and Google

Bruce wonders why Google seems to prefer separate chunks of JSON-LD in web pages instead of interwoven microdata attributes:

I strongly feel that metadata that is separated from the user-visible data associated with it highly susceptible to metadata partial copy-paste necrosis. User-visible text is also developer-visible text. When devs copy/ paste that, it’s very easy to forget to copy any associated metadata that’s not interleaved, leading to errors.

Heydon cracks me up—his Patterns Day is going to have you crying with laughter; guaranteed!

What Does it Mean to Be “Full Stack”? | CSS-Tricks

I’m not trying to convince anyone they aren’t a full-stack developer or don’t deserve that particular merit badge — just that the web is a big place with divergent needs and ever-morphing stacks that all require different sets of skills.

Web Bloat Score Calculator

Page web bloat score (WebBS for short) is calculated as follows:

WebBS = TotalPageSize / PageImageSize

Yes, this is a tongue-in-cheek somewhat arbitrary measurement, but it’s well worth reading through the rationale for it.

How can the image of a page be smaller than the page itself?

Lighthouse | Eric Bailey

What if accessibility were a ranking signal for Google search results?

Here’s a thought: what if Google put its thumb on the scale again, only this time for accessibility? What if it treated the Lighthouse accessibility score as a first-class ranking metric?

Welcome to Acccessible App | Accessible App

A very welcome project from Marcus Herrmann, documenting how to make common interaction patterns accessible in popular frameworks: Vue, React, and Angular.

Columbia & Elm; Fairfield & Gloucester. — Ethan Marcotte

Coffee talk with Ethan Marcotte. Today’s special: inclusivity.

I want to get there: to have nuanced discussions about text descriptions; I want to read poetry in alt text; to have our work’s success measured by how broadly it can be accessed; to create moving, beautiful experiences for people who may not use the web like I do.

Distinguishing cached vs. network HTML requests in a Service Worker | Trys Mudford

CSS-only chat

Test the impact of ads and third party scripts

This is a very useful new feature in Calibre, the performance monitoring tool. Now you can get data about just how much third-party scripts are affecting your site’s performance:

The best way of circumventing fear and anxiety around third party script performance is to capture metrics that clearly articulate their performance impact.

JavaScript pedalboard

The Simplest Ways to Handle HTML Includes | CSS-Tricks

Chris looks at all the different ways of working around the fact that HTML doesn’t do transclusion. Those ways include (hah!) Scott’s super clever technique and Trys’s little Sergey.

AMP as your web framework – The AMP Blog

The bait’n’switch is laid bare. First, AMP is positioned as a separate format. Then, only AMP pages are allowed ranking in the top stories carousel. Now, let’s pretend none of that ever happened and act as though AMP is just another framework. Oh, and those separate AMP pages that you made? Turns out that was all just “transitional” and you’re supposed to make your entire site in AMP now.

I would genuinely love to know how the Polymer team at Google feel about this pivot. Everything claimed in this blog post about AMP is actually true of Polymer (and other libraries of web components that don’t have the luxury of bribing developers with SEO ranking).

Some alternative facts from the introduction:

AMP isn’t another “channel” or “format” that’s somehow not the web.

Weird …because that’s exactly how it was sold to us (as a direct competitor to similar offerings from Apple and Facebook).

It’s not an SEO thing.

That it outright false. Ask any company actually using AMP why they use it.

It’s not a replacement for HTML.

And yet, the article goes on to try convince you to replace HTML with AMP.

Naming things to improve accessibility

Some good advice from Hidde, based on his recent talk Six ways to make your site more accessible.

How I failed the <a>

I think the situation that Remy outlines here is quite common (in client-rehydrated server-rendered pages), but what’s less common is Remy’s questioning and iteration.

So I now have a simple rule of thumb: if there’s an onClick, there’s got to be an anchor around the component.
